Abstract
The invention discloses an air-cooling radiating fin of a plate-fin type radiator, which comprises a plurality of fins and fin fixed connection composite plates. The fins and the composite plates which are adjacent are spaced mutually, side surfaces of the fins are approximately wavy, tops of the fins are straight, at least two bent unit which are formed by means of end-to-end connection are disposed on each of side surfaces of each fin, and an included angle of each bent unit ranges from 15 degrees to 75 degrees. The air-cooling radiating fin has the advantages that heat exchange efficiency is remarkably improved, and the air-cooling radiating fin is produced easily.
Description
Technical field
The present invention relates to the heat exchange equipment field, particularly relate to the fin of heat exchanger.
Background technology
Heat exchanger has been widely used in fields such as aviation, automobile, diesel locomotive, engineering machinery, air compression, air separation, petrochemical industry, air-conditioning, refrigeration at present.Wherein aluminum plate-fin heat exchanger at first obtains strong propelling in empty branch trade, and is as shown in Figure 1, and fin is the significant element that constitutes plate-fin heat exchanger, and heat exchanger is being brought in constant renewal in fin structure.Fin has two effects generally in heat exchanger structure: 1, supporting-core body structure, 2, participate in the exchange of heat as the secondary heat exchange face.The fin type of practical application at present has a lot, like flat type, zigzag, ripple type, undaform or the like.Satisfying under the required intensity prerequisite of support, what need consideration emphatically is exactly how on fin structure, to make improvement, to increase heat.Increase heat and mainly contain two technique directions, promptly how to increase heat exchange area and how to strengthen turbulent flow.Fin in use if working environment is more abominable, takes place and stops up in rippled fin easily, influences properties of product, need improve to boost productivity prior art.
Summary of the invention
The invention reside in the defective that has overcome prior art, the wind-cooling heat dissipating sheet of the plate fin type radiator that a kind of production efficiency is high, failure free time is long is provided.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
Comprise that a plurality of fins reach and the affixed composite plate of fin, two adjacent said fin and composite plate spaces, said fin side is similar to undulate, and said fin top is a flat, in said fin side, comprises the bend unit that two tandem arrays are processed at least.
Said bend unit is 15 °-75 ° of angles.
Compared with prior art, the present invention has following beneficial effect:
Strengthen properties of product, and can enhance productivity.
To the not high shortcoming of former money radiating efficiency, change the fin side into the setback face, make the fluid flow direction that gets into fin constantly change, air-flow produces disturbance, thereby has aggravated turbulent flow, has improved heat exchange efficiency.
Change fin top into flat shape, the rolling of band machine is rolled in the fin utilization at a high speed, has realized high speed machine production, thereby has improved production efficiency greatly.

The specific embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Shown in Fig. 2-6, the wind-cooling heat dissipating sheet of plate fin type radiator comprises that a plurality of fins 1 reach and affixed composite plate 2, two adjacent fins 1 and composite plate 2 spaces of fin; Fin 1 lateral surface is similar to undulate, and fin top is a flat, in said fin side; The bend unit 3 that a plurality of tandem arrays are processed, bend unit 3 are 15 °-75 ° of angles, make the fluid flow direction that gets into fin 1 constantly change; Air-flow produces disturbance, thereby has aggravated turbulent flow, has improved heat exchange efficiency.
The present invention is used for aluminum plate-fin heat exchanger; Change the fin side into the setback face in the fin cut-away portions; Form the concaveconvex shape of arranging according to certain rules, increase this concaveconvex shape is to prevent to occur in the product use fin to stop up as far as possible, and this kind fin can utilize high speed to roll the rolling of band machine; Realized high speed machine production, enhanced productivity.
The above is merely explanation embodiment of the present invention; Be not limited to the present invention, for a person skilled in the art, all within spirit of the present invention and principle; Any modification of being done, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. the wind-cooling heat dissipating sheet of a plate fin type radiator; Comprise that a plurality of fins reach and the affixed composite plate of fin, is characterized in that two adjacent said fin and composite plate spaces; Said fin side is similar to undulate; Said fin top is a flat, in said fin side, comprises the bend unit that two tandem arrays are processed at least.
2. the wind-cooling heat dissipating sheet of plate fin type radiator according to claim 1, it is characterized in that: said bend unit is 15 °-75 ° of angles.
